PREFERRED MODE FOR CARRYING OUT THE INVENTION First Embodiment

Hereinafter, embodiments of the present invention will be explainedwhile referencing the drawings, etc.

FIGS. 1A-1C are a plan view and cross-sectional views of a card 1 of afirst embodiment.

FIG. 1A is a plan view of the card 1 (view looking at the card topsurface (surface) 1 a from a normal line direction).

FIG. 1B is a cross-sectional view of the card 1 (cross-sectional viewalong the arrow b-b in FIG. 1).

FIG. 1C is an enlarged view inside of the two-dot dashed line c in FIG.1B.

It should be noted that, in the following explanation, the shape in theplan view (FIG. 1A) of the card 1 is called arbitrarily a planar shape.In addition, each figure illustrates the configuration relating to thehologram to be large.

The card 1 (laminated body) has a hologram layer 20 and surface layer 30laminated on a card substrate 10 from the bottom side Z1 (card backside) to the top side Z2 (card top surface (surface) side). Each ofthese layers is formed from a resin sheet material such as PET(polyethylene terephthalate), PET-G, PVC (polyvinyl chloride), andpolycarbonate. Between each layer can be bonded by an adhesion layer oradhesive layer, and can be bonded by thermocompression bonding.

The card 1 is applied to a credit card, etc., for example. For thisreason, the card 1 includes an IC chip, external contact terminal,contact-less communication coil antenna (for example, conducting wireantenna, etching antenna, etc.), magnetic strip, and a layer supportingthese components. Detailed explanations of these are omitted.

The card substrate 10 is a component serving as a base of the card 1. Itshould be noted that, although an example providing a layerconfiguration on the top side Z2 of the card substrate 10 is explainedin the first embodiment, a layer configuration may be provided also onthe bottom side Z1 of the card substrate 10, as necessary.

The color of the top surface of the card substrate 10 is black, andincludes on the order of about 1% carbon black, for example. The colorof the top surface of the card substrate 10 may be the as-is color ofthe card substrate 10, or in the case of making a printing on the topsurface of the card substrate 10, may be the color of this printing.

The hologram layer 20 is a layer in which a transparent hologram havingtranslucency is formed.

The transparent hologram is a Lippmann type of hologram. A Lippman typeof hologram is one coating a particular polymer layer on a film, andforming an interference fringe by the change in refractive index insidethis polymer layer. The Lippman type of hologram reproduces a hologramimage by the diffraction phenomenon, when light is incident on thisinterference fringe. The Lippman type of hologram excels in thepresentation of three-dimensionality and a sense of depth in top andbottom, and left and right directions, and three-dimensionality closerto the object of the genuine article is obtained. Because the materialsused and manufacturing process are unique, forgery is extremelydifficult, and thus the Lippmann type of hologram can improve theforgery prevention effect over a hologram of embossment type, forexample.

In the hologram layer 20, a hologram picture 21 of a globe is recorded.In the hologram picture 21, information (picture) is recorded in aportion of the land 21 a and out line 21 b, and an ocean 21 c and anexternal portion 21 d more outside the out line 21 b are transparent.For this reason, the portions of the land 21 a and out line 21 b areseen three-dimensionally. In addition, for the ocean 21 c and inside ofa window portion 44 (described later) of the external portion 21 d, thetop surface of the card substrate 10 can be confirmed by sight by lightpenetrating.

As shown in FIG. 1A, the outer shape of the hologram layer 20 is smallerthan the outer shape of the card 1. In other words, the hologram layer20 is laminated only on a region of a part of the card substrate 10.This is for reducing the cost by reducing the hologram layer 20, whichis expensive.

The surface layer 30 is laminated upper direction Z2 than the cardsubstrate 10 and hologram layer 20.

The surface layer 30 is formed by a transparent material.

The top surface of the surface layer 30, i.e. card top surface 1 a, isformed as a mirror finished surface. It should be noted that, due to thecard top surface 1 a being a mirror finished surface, the hologrampicture 21 is sharply observed, which can improve thethree-dimensionality.

A print layer 40 is provided on the top surface of the surface layer 30.

The print layer 40 is formed by pressurizing a transfer foil provided onPET onto the top surface of the surface layer 30 with plates totranscribe. The top surface of this plate may be mirror finished surfaceform, or a matt form; however, the matt form is preferred because thetranscription suitability is better than the mirror finished surfaceform, and convexities in the card due to foreign matter are smaller. Itshould be noted that, in either case, it is possible to form the cardtop surface 1 a as a mirror finished surface.

The print layer 40 is a layer printed in a similar color black as thecard substrate 10. The print layer 40 contains carbon black on the orderof 15 to 30%, for example.

In a planar shape, the portion 41 of the print layer 40 overlapping theedge portion 22 of the hologram layer 20 and a region 42 in the vicinitythereof are color shadings the same or substantially the same as thecard substrate 10.

The print layer 40 has a gradation portion 43.

The gradation portion 43 is a portion gradation printed so that thecolor shadings become lighter as approaching further inside from theexterior edge portion 43 a located in more inside than the edge portion22 of the hologram layer 20. The color shadings inside the gradationportion 43 become gradually lighter from 100% at the exterior edgeportion 43 a to 0% at the interior edge portion 43 b. The portion moreinside than the interior edge portion 43 b of the gradation portion 43becomes the window portion 44.

In the window portion 44, the transparent surface layer 30 is completelyexposed. For this reason, the entirety of the hologram picture 21 of thehologram layer 20 can be confirmed by sight from the window portion 44.

Next, the appearance of the card 1 from the top side Z2 will beexplained.

(Vicinity of Edge Portion 22 of Hologram Layer 20)

As described previously, the portion 41 of the print layer 40overlapping the edge portion 22 of the hologram layer 20 and the region42 in the vicinity thereof are color shadings the same or substantiallythe same as the card substrate 10. For this reason, the edge portion 22of the hologram layer 20 is concealed by the print layer 40 (refer toarrow A). Furthermore, since the card substrate 10 and print layer 40are dark colors, which absorb light, the edge portion 22 of the hologramlayer 20 can almost not be confirmed by sight.

(Gradation Portion 43)

Only the color of the print layer 40 is confirmed by sight at theexternal edge portion 43 a of the gradation portion 43. Since thehologram layer 20 is transparent, the card substrate 10 can be graduallyconfirmed by sight as approach the inside from the external edge portion43 a. Additionally, it is configured so that only the color of the cardsubstrate 10 is confirmed by sight at the internal edge portion 43 b ofthe gradation portion 43 (refer to arrow B). Furthermore, the printlayer 40 and card substrate 10 are the same color black. For thisreason, the print layer 40 and card substrate 10 are confirmed by sightto be integrated like a seamless identical component.

(Window Portion 44)

Inside of the window portion 44, the print layer 40 is not formed on thesurface layer 30; therefore, it is possible to confirm the hologrampicture 21 of the hologram layer 20. Since the hologram is a transparenthologram, the color of the card substrate 10 is confirmed by sight atthe back thereof. In addition, as previously mentioned, the print layer40 and card substrate 10 are confirmed by sight to be seamlesslyintegrated.

For this reason, the periphery of the hologram picture 21 is observedsuch that the back in black is present in a wider range than thehologram layer 20. In addition, since the portion of the ocean 21 c ofthe hologram picture 21 is transparent, the color of the card substrate10 is confirmed by sight.

Thereby the portions of the land 21 a and outline 21 b of the globeappear to be float up from the black background and the hologram picture21 is observed more three-dimensionally.

It should be noted that the above-mentioned visual effect of the card 1of the first embodiment has been confirmed by experiments.

As explained above, the card 1 of the first embodiment, even in the caseof the hologram layer 20 being provided only to a partial region, canimprove the effect of the hologram being seen three-dimensionally fromthe entirety of the card 1. In addition, it is thereby possible toproduce a high quality sensation.

Furthermore, even though the Lippmann type of hologram is transparent,it has a greater visual effect to be seen three-dimensionally than anembossed hologram, for example. The card 1 of the first embodimentemploys this characteristic of Lippmann type holograms, whereby the cardsubstrate 10 disposed on the back side of a transparent hologram layer20 can be seen, and the hologram picture 21 appears three-dimensionally.

Furthermore, the Lippmann type hologram is difficult to forge, andsophisticated manufacturing techniques are further required toaccommodate the hologram layer 20 inside of the card 1 and to make theedge portion 22 of the hologram 20 inconspicuous by the aboveconfiguration. For this reason, it is possible to improve the effect offorgery prevention of a credit card or the like.

Second Embodiment

Next, a second embodiment of the present invention will be explained.

It should be noted that, in the explanation and drawings for each of thefollowing embodiments, the same reference symbol or the same referencesymbol at the end (last two digits) is assigned to a portion fulfillinga similar function as the aforementioned first embodiment, andexplanations that would be redundant are omitted as appropriate.

FIGS. 2A and 2B are a plan view and cross-sectional views of a card 2001of a second embodiment.

FIG. 2A is a plan view of a card 201 (view looking at card top surface(surface) 201 a from normal line direction).

FIG. 2B is a cross-sectional view of the card 201 (cross-sectional viewalong the line b-b in FIG. 2).

FIG. 2C is a cross-sectional view of the card 201 (cross-sectional viewalong the line c-c in FIG. 2).

It should be noted that illustrations of cross-sectional forms of theemboss 270 have been omitted in FIG. 2B and FIG. 2C.

The card 201 includes a card substrate 210, hologram layer 220, surfacelayer 230, magnetic strip 231, upper print layer 240, bottom layer 250,lower print layer 260, and emboss 270.

The card substrate 210 includes a lower substrate 211 and uppersubstrate 213, and an adhesion layer 212 bonding between the lowersubstrate 211 and upper substrate 213. In other words, in the card 201,the card substrate 210 is formed by the two layers of the lowersubstrate 211 and upper substrate 213.

The lower substrate 211 and upper substrate 213 are layers of the samematerial properties and same thickness. Between the lower substrate 211and upper substrate 213, a functional component such as an electroniccomponent is not provided, and only the adhesion layer 212 is present.In other words, the card substrate 210, although a single-layerconfiguration is originally possible, is made a two layer configurationfor processing performance during the embossing processing, a durabilityimprovement against bending, etc. as described later.

The hologram layer 220 is formed by a hologram formation layer 226 andhologram protective layer 227 being laminated on order from the bottomside Z1.

The hologram formation layer 226 is a similar component to the hologramlayer 220 of the first embodiment. The hologram formation layer 226 isadhered on the top surface of the upper substrate 213 by a transparentheat-seal layer 225.

The hologram protective layer 227 is a protective sheet that protectsthe hologram formation layer 226. The hologram protective layer 227 isadhered on the top surface of the hologram formation layer 226. Thehologram protective layer 227 is formed by transparent PET or the like.

Herein, the production processing of the card 201 includes apressurizing step, heating step, etc. By providing this hologramprotective layer 227, in the card 201, the collapse of the hologramstructure of the hologram formation layer 226 can be suppress in thesesteps. It should be noted that the suppressing effect has been confirmedby comparative study and experiments.

The surface layer 230 and upper print layer 240 are the same as thesurface layer 30 and print layer 40 of the first embodiment.

It should be noted that a bonded structure is not provided between thelower surface of the surface layer 230 and top surface of the hologramprotective layer 227.

For this reason, between the lower surface of the surface layer 230 andthe top surface of the hologram protective layer 227 is configured sothat between the top surface of the upper substrate 213 and the lowersurface of the surface layer 230 is adhered around the hologram layer220, whereby lifting (peeling) is suppressed.

The magnetic strip 231 is laminated on the top surface of the surfacelayer 230. The magnetic strip 231 is arranged in a region other than thewindow portion 44 and gradation portion 43 in a plan view. For thisreason, the magnetic strip 231 is configured so as to be concealed bythe upper print layer 240 and not to be visible from the card uppersurface 201 a.

Information relating to the bank account number, etc. of a bank orcredit company is recorded in the magnetic strip 231. This informationcan be read using a reader (not illustrated).

The bottom layer 250 is the same component as the surface layer 230. Inother words, in the card 201, a layered configuration is provided alsoon the bottom side Z1 of the card substrate 210. A magnetic strip, etc.is provided on the bottom layer 250 as necessary, similarly to thesurface layer 230.

The lower print layer 260 is provided on the top surface of the bottomlayer 250. The print layer is formed by transcribing a transcriptionfoil provided on PET. In other words, the lower print layer 260 isformed similarly to the upper print layer 240. However, the lower printlayer 260 does not include the gradation portion 43 and window portion44. This is because the card 201 is not of a specification for observinga hologram picture from the lower surface. The lower print layer 260 hasvarious information (characters, symbols, graphics), design picture,etc. of the card 201.

It should be noted that the lower print layer 260 is covered by thelower layer 250 and not exposed; therefore, it can suppress staining.

The emboss 270 is arranged not only outside of the window portion 44,but also inside of the window portion 44, i.e. on the hologram layer220, in a plan view.

The emboss 270 is formed so as to make a convexity on the top side Z2,on the top surface of the card 201.

Examples of the material, thickness and color of the main layers are asbelow from the top side Z2.

Surface layer 230: transparent, 50 μm, PET-G, Mitsubishi Resins, PG-MCT

Upper substrate 213: black, 300 μm, PET-G, Mitsubishi Resins, BG-WSE

Adhesion layer 212: transparent, polyester resin, transparent 100 μm (50μm×2 layers), Toagosei Co., Ltd., PES-111EE

Lower substrate 211: same as upper substrate 213

Bottom layer 250: same as surface layer 230

It should be noted that the adhesion layer 212 was made in a two-layerconfiguration in order to adjust the thickness. If a 100-μm adhesionlayer can be obtained commercially in a single layer, the adhesion layer212 may employ this.

The color of the card lateral surfaces will be explained.

The adhesion layer 212 is transparent. In addition, although explanationand illustration are omitted, between the other layers (e.g., betweenupper substrate 213 and surface layer 230), a transparent adhesion layerthat bonds between these is also included. The layers exposed at otherlayer surfaces (lower substrate 211, upper substrate 213, etc.) areblack.

Herein, the transparent layers have a tendency to be observed as blackwhen seen from the card lateral surfaces. For this reason, the entiretyof the lateral surfaces is observed as black, thereby the appearance ofthe card 201 is not disfigured.

(Comparison with Comparative Examples of Emboss Appearance)

As mentioned above, the card substrate 210 is configured by bondingbetween the lower substrate 211 and upper substrate 213 with theadhesion layer 212. It has thereby been confirmed by performing actualexperiments that the card 201 can improve the appearance of the emboss270, according to comparison with Comparative Examples.

FIGS. 3A-3B are cross-sectional views schematically showing crosssections in the vicinity of an embossed part of the second embodimentand a comparative example.

FIG. 3A is a cross-sectional view (cross-sectional view of 3 a-3 a partin FIG. 2) in the vicinity of an embossed part of the second embodiment.

FIG. 3B is a cross-sectional view in the vicinity of the embossed partof a comparative example.

FIGS. 4A-4B are cross-sectional views of a state in which the card 201of the second embodiment or card 101 of the comparative example are bentso as to make a convex shape to the top side Z2.

FIG. 4A is a cross-sectional view of the card 201 of the secondembodiment.

FIG. 4B is a cross-sectional view of the card 101 of a comparativeexample.

As shown in FIG. 3B, the card 101 of the comparative example has thecard substrate 110 formed by a sheet of one layer. In the card substrate110, the materials are the same as the lower substrate 211 and uppersubstrate 213 of the second embodiment, and the thickness is the same asthe thickness from adding the lower substrate 211 and upper substrate213.

In the card 101 of the comparative example, a space A was generatedbetween the top surface of the hologram protective layer 127 and thelower surface of the surface layer 130 around the emboss 170 afterembossing. This is considered a phenomenon in which a part of thesurface layer 130 and hologram protective layer 127 have peeled away.

On the other hand, such a space A did not occur in the card 201 of thesecond embodiment.

One of the causes for the space A being generated in the card 101 of thecomparative example in this way is considered to be for the followingreason.

As shown in FIG. 4A, the lower substrate 211 and upper substrate 213 ofthe second embodiment are laminated via the adhesion layer 212;therefore, a certain displacement in the planar direction (XY planedirection) is permitted during bending in an effect to deformindividually.

On the other hand, as shown in FIG. 4B, the card substrate 110 of thecomparative example is formed from one layer; therefore, it is made todeform as one body during bending. For this reason, a radius ofcurvature R110 during bending of the card substrate 110 of thecomparative example is larger than the radius of curvature of the cardsubstrate 210 of the second embodiment by the thickness of the lowersubstrate 211 and adhesion layer 212.

For this reason, the elongation amount of a top surface vicinity 110 aof the card substrate 110 of the comparative example becomes larger thanthe elongation amount of a top surface vicinity 210 a of the uppersubstrate 213 of the second embodiment.

The same phenomenon is considered to happen also during embossing.

As shown in FIG. 3B, for this reason, the elongation amount of the uppersurface vicinity 110 a of the card substrate 110 of the comparativeexample becomes a larger elongation amount than the upper surfacevicinity 210 a of the card substrate 210 (upper substrate 213) of thesecond embodiment. It should be noted that, since the hologram layer isarranged on the top surface of the card substrate, if the card substratetop surface is elongated, it will elongate integrally with the cardsubstrate top surface.

For this reason, the stress occurring in the hologram protective layerbecomes larger as the elongation amount of the top surface of the cardsubstrate increases. For this reason, the stress of the hologramprotective layer 127 of the comparative example becomes larger than thestress of the hologram protective film 227 of the second embodiment.This stress is considered to be one occurrence factor of the space A atthe hologram protective layer 127 of the comparative example.

In contrast, the card 201 of the second embodiment could suppress theoccurrence of such a space A by bonding the lower substrate 211 andupper substrate 213 with the adhesion layer 212.

In addition, during bending as shown in FIG. 4, the card 201 canmaintain an improvement in peeling suppression between the surface layer230 and hologram protective layer 227 for the above reason. For thisreason, the card 201 can maintain the inhibiting effect of degradationin the appearance caused by repeat bending, and thus can improvedurability.

(Reason for Embedding Hologram Layer 220 Inside Card)

The card 201 of the embodiment is not laminating the hologram layer 220on the card top surface 201 a, but rather is a form embedding in thebottom side Z1 of the surface layer 230. The reason for embedding inthis way is because there is a possibility of the function required inthe card to decline more than conventionally if laminated on the cardupper surface. For example, there is the following function.

In this case, since the magnetic strip will be arranged more to thebottom side Z1 than the hologram layer, the information readingperformance of the reader will be inferior.

Although a silver foil must be transcribed to the top surface of theemboss, in this case, it is difficult for the silver foil to betranscribed to the surface of the hologram layer.

In this case, a Lippmann hologram layer is arranged as the topmostsurface. The Lippmann hologram layer tends to be weak to embossing, andthus breaking tends to occur. It should be noted that, if breakingoccurs in the topmost surface, the emboss will split down to the bottomlayer thereof, starting from this break.

In this case, since peeling of the hologram layer is easy, the forgeryinhibitory effect becomes little, and the security may decline.

In addition, in the case of laminating the hologram layer on the cardtop surface, the hologram layer must be laminated on the entirety of thetop surface of the surface layer. This is because, if the hologram layeris made smaller than the surface layer 230, since the outer edge portionof the hologram layer will be visible, the appearance will be inferior.In the case of laminating the hologram layer in this way over theentirety of the top surface of the surface layer 230, since theexpensive Lippmann hologram layer will become larger, the card will alsobecome high cost.

In other words, the card 201 of the embodiment maintains theabove-mentioned functions, and by embedding the hologram layer 220inside and providing the gradation portion so as to enable production atlow cost, the hologram layer 220 is formed to be small without allowingthe appearance to decline.

As explained above, the card 201 of the present embodiment can improvethe emboss processability and durability to bending. In addition, themagnetic strip 231, etc. of the card interior can be concealed, and thusthe appearance can be improved.

Third Embodiment

Next, a third embodiment of the present invention will be explained.

FIGS. 5A-5C are a plan view and cross-sectional views of a card 301 of athird embodiment (drawing corresponding to FIG. 2).

The card 301 has the following different configurations when comparedwith the second embodiment.

The card 301 does not have a magnetic strip 231 (refer to FIG. 2)provided.

The card 301 has an upper print layer 340 provided on the lower surfaceof the surface layer 230.

Since the card 301 does not have the magnetic strip 231 provided, it isnot necessary to conceal this. For this reason, the upper print layer340 is arranged on the lower surface of the surface layer 230.

The card 301 thereby exerts the following effects. Since the upper printlayer 340 is not exposed, it is possible to suppress staining of theupper print layer 340.

In addition, only the hologram layer 320 is present between the upperprint layer 340 and top surface of the upper substrate 313 in thelaminating direction Z at the gradation portion 43.

For this reason, the distance between the upper print layer 340 and thetop surface of the upper substrate 313 is smaller than in the secondembodiment. The sense of unity between the black color of the upperprint layer 340 and the black color of the upper surface of the uppersubstrate 313 is thereby improved, whereby an improvement in appearancecan be maintained.

As explained above, the card 301 of the present embodiment can suppressstaining of the upper print layer 340. In addition, the sense of unityof the upper print layer 340 and upper substrate 313 is improved,whereby the improvement in appearance can be maintained.

Fourth Embodiment

Next, the fourth embodiment of the present invention will be explained.

FIG. 6 is a plan view and cross-sectional views of a card 401 of afourth embodiment.

The card 401 has the following different configurations when comparedwith the second embodiment.

A black silk-screening layer 414 (printing adhesive layer) is includedon the top surface of the upper substrate 413.

The top surface of the upper substrate 413 is a matt surface 413 ahaving surface irregularities.

The lower surface of the surface layer 430 is a matt surface 430 ahaving surface irregularities.

Herein, matt surface refers to a surface with irregularities in thesurface. Matt finishing employs a technique of spraying fine sand onto aplastic film by sand blasting, or forming irregularities of a pressingplate in the plastic film, etc., for example.

The silk-screening layer 414 has an adhesive material between the topsurface of the upper substrate 413 and the lower surface of the surfacelayer 430, and an adhesive material between the top surface of the uppersubstrate 413 and the lower surface of the hologram layer 420.

The matt surfaces 413 a and 430 a can improve the bonding performance ofthe silk-screening layer 414 by increasing the bonding area. In otherwords, the matt surfaces 413 a and 430 a can improve the adhesivenessbetween the top surface of the upper substrate 413 and lower surface ofthe surface layer 430, and the adhesiveness between the top surface ofthe upper substrate 413 and the lower surface of the hologram layer 420.

Herein, the matt surfaces 413 a and 430 a may appear wavy when observedfrom the card top surface (surface) 401 a.

With the present embodiment, this phenomenon of appearing wavy isdecreased by providing the black silk-screening layer 414, whereby theappearance can be improved.

In other words, the card 401 of the present embodiment provides the mattsurfaces 413 a and 430 a to the top surface of the upper substrate 413in order to improve adhesiveness, and further provides thesilk-screening layer 414 so as to remarkably improve the bondingperformance and now allow the appearance to decline.

As explained above, the card 401 of the present embodiment can improvethe adhesiveness between the upper substrate 413 and the surface layer430 and the adhesiveness between the upper substrate 413 and thehologram layer 420, without allowing the appearance to decline.

It should be noted that, since the present embodiment has the blacksilk-screening layer 414, the substrate color itself of the uppersubstrate 413 may not be black. This is because, when observing the cardtop surface 401 a, the upper substrate 413 is concealed by thesilk-screening layer 414.

In addition, the configuration of the present embodiment may be appliedto the third embodiment. In this case, since the distance between thesilk-screening layer 414 and upper print layer 440 in the laminatingdirection Z becomes small, the appearance improving effect can beimproved.

Although embodiments of the present invention have been explained above,the present invention is not to be limited to the aforementionedembodiments, and various modifications or changes are possible as in themodified embodiments described later, and these are also within thetechnical scope of the present invention. In addition, the effectsdescribed in the embodiments are merely listing of most ideal effectsproduced from the present invention, and the effects from the presentinvention are not to be limited to the matters described in theembodiments. It should be noted that the aforementioned embodiments andmodified embodiments described later can also be employed by combiningas appropriate; however, a detailed explanation is omitted.

Modified Embodiments

(1) In the embodiment, an example is illustrated in which the card topsurface is a mirror finish surface; however, it is not limited thereto.For example, the card top surface may be finished to matt form havingsurface irregularities (frosted finish). In this case, the edge portionof the hologram layer can be more obscured by decreasing the lightpenetrating the surface layer; therefore, the effect of screening theedge portion of the hologram layer can be improved. In addition,scratches in the top surface can be made inconspicuous.

It should be noted that, in matt finishing the card top surface, it issufficient so long as providing a step of pressing the card top surfacewith a plate in which a matt shape is formed.

(2) The embodiments illustrate examples in which the hologram layer isof Lippmann type; however, it is not limited thereto. For example, thehologram layer may be of emboss type.(3) The embodiments illustrate examples in which the gradation portiondoes not overlap a picture portion of the hologram; however, it is notlimited thereto. The gradation portion may be formed so as to overlapthe picture portion of the hologram, and the color shadings to becomelighter approaching the inside. In this case, the picture can beobserved so that the periphery blurs and becomes shaper approaching theinside, by way of the gradation portion.(4) The embodiments illustrate an example in which the laminated body isa card; however, it is not limited thereto. For example, the laminatedbody may be employed in a coupon or the like.(5) The embodiments illustrate examples in which the color of the printlayers and card substrates are black; however, it is not limitedthereto. For example, the color of the print layers and card substratesmay be anything so long as the same color. In addition, irrespective ofthe color of the card substrates and print layers, it is sufficient solong as there is an effect of the print layer concealing the edgeportion of the hologram layer.(6) The second and third embodiments illustrate examples in which thecard substrate is configured by two layers (upper substrate and lowersubstrate); however, it is not limited thereto.
